Dipeptidyl carboxypeptidase-deficient mutants of Salmonella typhimurium.
J. Bacteriol. 153(3) , 1252-8, (1983) Mutants of Salmonella typhimurium deficient in dipeptidyl carboxypeptidase have been isolated by screening for clones unable to use N-acetyl-L-alanyl-L-alanyl-L-alanine (AcAla3) as the sole nitrogen source. An insertion of the transposable element Tn10 near d... |
